Replace
:M-[IDU]*
with
:C/-([IDU])[ ]*/-\1/Wg:M-[IDU]*
so that arguments with whitespace after them work correctly.
Resolves [toolchain/18248] from Andrew White at Motorola.
Be consisent in this syntax; previously we'd sometimes we'd just have :M-[ID]*
which would ignore -Ufoo ...
(This needs :C///W support in make(1) that Simon Gerraty added for me :)
